The thus-obtained phenyl-β-naphthyl-3-methoxyphenylamine was dissolved in 250 ml of toluene, and 25 g of anhydrous aluminum chloride was added thereto. The resulting mixture was heated under reflux for 2 hours. After being allowed to cool down, the reaction liquor was poured into ice water and then rendered acidic by adding hydrochloric acid. The organic phase thus-obtained was separated and the toluene was concentrated under reduced pressure. Crystals precipitated were collected by filtration to obtain 24 g of phenyl-β-naphthyl-3-hydroxyphenylamine.
